Irradiance of the area per unit frequency or wavelength. The phrases spectral flux density or even more confusingly "spectral depth" may also be applied. Non-SI models of spectral irradiance include Jansky = 10 W⋅m⋅Hz and solar flux unit (1SFU = ten W⋅m⋅Hz). In the event the beam of light https://dalei319foy7.wikijm.com/user
